I know this cmd but it doesn’t give you access if the “Administrator” account is not password protected and if it is or if you try the same cmd with other administrator account which supports a password , a new cmd prompt will appear but actually it doesn’t run as administrator, so this cmd doesn’t change anything (if you tried it you know what I m talking about)

But thanks for your interest!

You can use runas command to run the command prompt as administrator but you need to specify password after run the command:

“runas /user:Administrator cmd”

Reference: Runas

does anyone know how to run a cmd prompt with administrative privilleges through a java program?

Thanks in advance!

But thanks anyway for the great article & thread!

String cm = ” rmdir /q /s ” + dir;
Process process = Runtime.getRuntime().exec(“cmd /c ” + cm);
int exitVal = process.waitFor();

If I try to run it from Eclipse, it executes well.
If I generate a (fat) jar from it, and start it from the
DOS window, it hangs forever.

Do you have any hint?

You should use Java applet if you want to develop Java application on web.

I have a similar problem as Kevin (above) but some of the os-agnostic applications I am launcing do not have a /q or “quite mode”. Is there any way to create a 2-way interactive process or thread?

I have the following:

String line="";
BufferedReader br;
br = new BufferedReader(new InputStreamReader(System.in));
StringBuffer s2 = new StringBuffer();
Runtime oShell = Runtime.getRuntime();
String oSysName = System.getProperty("os.name" );
if(oSysName.toUpperCase().startsWith("WIN")) {
// We need to make this OS Agnostic
line = "cmd.exe /c "+getPath(sCommand)+".cmd"; // Shell Out to Win32
} else { line = "/bin/sh -c "+getPath(sCommand); } // Shell to UNIX, Linux or MAC
String args[] = line.split("[ \t]+"); // tokenize the commandLine into an array for exec()
System.out.println("\n SHELL> Type any additional parameters, end with ^D (UNIX) or ^Z (Win32) + [Enter] \n\n");
do {
line = br.readLine();
if (line != null) { args = addArrayNode (args, line); }
} while (line != null);
System.out.print(" SHELL> Executing Command, Please Wait... ");
System.out.print("\n\n The Following String is being sent to "+oSysName+ " for processing:\n\t"+Arrays.toString(args));
Process oProc = oShell.exec(args); //Process Launcher
// create reader to get errors as a character stream from the child process...
final BufferedReader errorHandler =
new BufferedReader(new InputStreamReader(oProc.getErrorStream()));

// create reader to get standard output as a character stream from child process...
final BufferedReader outputHandler =
new BufferedReader(new InputStreamReader(oProc.getInputStream()));


Then I launch threads to capture and display the output. such as:


//Get and display the standard output produced by the child process...(for non-ERRORs)
Thread stdoutThread = new Thread() {
public void run() {
try { int l; String line;
for(l = 0; (line = outputHandler.readLine()) != null; ) {
if (line.length() > 0) { l++; outputLines.addElement(line); }
System.out.println(line);
}
if (l >0) System.out.print("\n\nRead " + l + " lines (above) from stdout.");
outputHandler.close();
} catch (IOException ie) { System.out.println("SHELL> IO exception on stdout: " + ie); }
}
};//end-sddoutThread-def


I’m having a hard time getting my head around the (interactive scenario’s) thread handler. How do I know if it needs a response? Which thread should I watch? Both? Maybe use: getOutputStream ???

not sure if my code snippits will be formatted properly, but any help would be greatly appreciated..
